Free parser software for mac

ANTLRWorks 1.3b brings users a novel grammar development environment for ANTLR v3 grammars, which combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-agnostic debugger for isolating grammar errors. ANTLRWorks allows users to edit, visualize, interpret and debug any ANTLR 3 grammar through an easy-to-use graphical user interface.

ANTLRWorks helps eliminate grammar nondeterminisms, one of the most difficult problems for beginners and experts alike, by highlighting nondeterministic paths in the syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars more accessible to the average programmer, improve maintainability and readability of grammars by providing excellent grammar navigation and refactoring tools, and address the most common questions and problems encountered by grammar developers

Major Features:

1. Editor
   • Single window editing
   • Syntax highlighting
   • Rule navigation tree
   • Jump to rule or token definition
   • Go To Rule
   • Find usages of tokens or rules
   • Find and Replace using regular expression
   • Sensitive keyword, rule, and token auto-completion
   • Rules and actions folding
   • Tips and ideas
   • Auto-indentation
   • Refactoring - remove left recursion, extract or inline rule, etc.
   • Show generated lexer or parser code using syntax coloring
   • Syntax diagram display for lexer and parser rule
   • Show unreachable alternative(s) in syntax diagram
   • Display nondeterminism warning as ambiguous paths through the syntax diagram
   • Highlight decision DFA
   • Rule dependency graph
   • Export syntax diagram, NFA and parse tree to bitmap image or EPS file
   • Perforce integration
   • emacs key bindings (Mac OS X only)
   • Contextual menus
   • Print
2. Grammar interpreter
   • Dynamically interpreter any input text
   • Display parse trees as list or graph
3. Grammar debugger
   • Local or remote debugger
   • Language agnostic
   • Dynamic parse tree
   • Dynamic AST
   • Tree grammar debugging
   • Lookahead highlighting
   • Breakpoint in grammar
   • Breakpoint in input text!
   • Breakpoint on any events - LT, consume token, exception, etc.
   • Step over rule
   • Show corresponding grammar location and parse tree node for each input token
   • Detachable panels
4. Code generation:
   
   • ANTLRWorks supports code generation in any language that ANTLR knows how to generate via the output=language option.
   • For Java, however, ANTLRWorks knows how to build a test harness, compile everything, launch the parser, and connect to it--a great rapid prototyping feature when you can't use the interpreter because actions and/or semantic predicates must execute.

Enhancements:

• New Grammar Wizard
• StringTemplate Editor
• Custom test rig
• Run an input directly on the grammar

easyEST is a bioinformatics package to analyze ESTs (Expressed Sequence Tags) easily.
easyEST contains functionalities of ESTs for EST submission, Batch BLAST and BLAST result parser, etc. easiEST contains JAVA GUI applications for analyzing ESTs or other sequences.

System requirements:
- Java

You can click through the feeds on the left, use the (hopefully self-explanatory) icons next to them to manipulate them and do all the other stuff a RSS reader should do.
blindRSS is programmed so that the feeds will be re-read by a daemon or a cronjob and as much functionality as possible is done within the client. Thus the server only does what it is supposed to do: serve data.

System requirements:
- PHP-enabled web server

Enhancements
New Features:
- Settings window no longer autohides when mouse leaves window
- Options got their own window.
- Option "PurgeAfter" added. Defines when entries are to be automatically deleted
- Options now saved on server
Changes:
- new rss-parser (MagpieRSS)

Force Content-Type is an extension to force the Content-Type of URLs.
Force Content-Type its useful to avoid the tag soup when you are developing a XHTML webpage and want Firefox to use its internal XML parser.
If the webserver is not correctly configured, it will serve the page with a text/html Content-Type (a tag soup), instead of sending it as application/xhtml+xml, and therefore avoiding Firefox to treat the page as pure XML.

System requirements:
- Firefox 1.5 or later.

Ruby/ActiveLdap will allow you to easily map LDAP entries to Ruby objects with LDAP attribute accessors based on your LDAP servers schema and each objects objectClasses.

Enhancements
- Removed Base64 module use.
- Improved LDIF parser.
- Improved scheme parser.
- Supported Base64 in XML serialization.
- Supported TLS options.
- Supported ActiveRecord 2.2.2.
- Supported Ruby on Rails 2.2.2.
- Used rails/init.rb and rails_generators/ directory structure convention for Rails and gem. rails/ directory will be removed after 1.0.2 is released.
- AL-Admin migrated to Ruby on Rails 2.2.2 form 2.0.2.
- Improved ActiveDirectory integration.
- Accepted :class_name for belong_to and has_many option.
- Improved default port guess.

- [#9][#16] Reduced raising when DN value is invalid. [danger1986][Alexey.Chebotar]
- [#10][#12] Fixed needless , is appeared. [michael.j.konopka]
- [#11] Required missing active_ldap/user_password. [michael.j.konopka]
- [#13] Returned entries if has_many :wrap has nonexistent entry. [ingersoll]
- [#15] Fixed type error on computing DN. [ery.lee]

Jreepad allows you to store and edit all your little nuggets of text in an incredibly intuitive tree structure. Each "node" on the tree has a plain-text "article" associated with it, meaning that a Jreepad file becomes almost a freeform database, storing all kinds of information.
Write to-do lists, plan the structure of your book, keep a library of code snippets... people use it for all sorts. Jreepad runs from a thumbdrive on both Macs and PCs - its highly portable and useful.

Enhancements
- Some new things since 1.5: option for file encryption; font size of tree/article can be altered; context-menu added; SAX XML parser used for XML goodness. Thanks to all who contributed towards this release.
